Jewelry Identifier & Appraisal
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
What is my jewelry worth? Snap a ring, necklace, watch or gem to see what it is and an estimated value from real sold prices. Plus measure your ring size.
What is my jewelry worth? Primo Jewelry is a jewelry identifier and jewelry appraisal app with a ring sizer built in. Snap one photo of a ring, necklace, bracelet, watch, antique brooch, costume jewelry piece or loose gemstone, and the AI tells you what it is and what it could sell for.
JEWELRY VALUE FROM REAL SOLD PRICES
Take a single photo and the AI identifies the piece (type, likely metal, stones and style), then estimates its value from real sold prices on online marketplaces, not asking prices or guesswork. You get an estimated resale value, a price range, and the comparable sold listings behind it.
IDENTIFY JEWELRY, GEMS AND WATCHES
- Rings, necklaces, bracelets, earrings, pendants and brooches
- Loose gemstones, pearls and diamond jewelry
- Watches, from the dial markings and style
- Antique, vintage and costume jewelry
- Hallmarks and stamps such as 14K, 925 or PT950, read from the photo when they are visible
RING SIZER
No printable strips and no guessing. Place a standard bank card next to your ring or finger, take two photos, and Primo Jewelry measures the inner diameter and gives your US ring size plus UK, EU and JIS equivalents, circumference and neighbouring sizes.
